Hi,

I was playing a backup game with the 3.55 Kmeaw, now i have a new PS3 with the 3.70 version and the original copy of this game. I've took the saved game from the 3.55 PS3 and transfer to the new one, but the original copy is in other region one is BLES01047 and the other BLUS30339. How can i edit the param.sfo?
